We report a case of ring chromosome 13 with a distal deletion of 13q32.2→qter observed in a fetus who was referred to our institution at term due to severe growth restriction and multiple congenital malformations on ultrasonographic examination. This boy was born by vaginal delivery at 39 weeks in gestation. His weight, head circumference and height were less than the 3 percentile of gestational age. Apgar score was 7 at 1 minute and 9 at 5 minutes. He showed microcephaly, large forehead, low set ears, hypertelorism, flat nasal bridge, and micrognathia. The genitalia was ambiguous, showing severe hypoplasia of the penis. The anus was ectopic, displaced anteriorly from its normal position but with a normal opening and function. Neurologic examination was normal. Echocardiogram done at 2 weeks of life showed a persistent foramen ovale and a ventriculoseptal defect (type II) with increased pulmonary hypertension. MRI examination of the brain showed poorly demarcating corpus callosum suspecting agenesis of corpus callosum. Also, cerebellar vermis was small and hypoplastic, mimicking a variant form of Dandy-Walker malformation. MRI of the pelvis showed a tubular structure in pelvic cavity, suspicious of uterine remnant, between urinary bladder and rectum, and a inguinal hernia was noted in the left side. In the abdominal cavity enlarged adrenal glands were noted, and hormonal study showed elevated 17-α-OH-progesterone (168.9 ng/ml) with normal 17-KS and 17-OHCS levels. Gastrointestinal and urogenital system were otherwise normal. Cytogenetic analysis of the parents were both normal but the newborn showed 46, XY, r(13), de novo, with deletion points q32.2→qter. Our findings are in line with previous reports about chromosome 13 deletions, in which loss of the critical point leads to major malformations like brain anomalies and ambiguous genitalia.

목적: 임신 제일삼분기에 절박유산으로 진단받은 임신부에서 임신 20주 이후까지 성공적으로 임신이 유지된 군과 자연유산이 일어난 군에서 배아심박수의 차이를 알아보고자 한다. 방법: 연구 대상은 86명이었으며 임신이 20주 이상 지속된 경우가 73명 자연유산이 일어난 경우가 13명이었다. 절박유산 진단 시 두 군의 평균 심박수에 차이가 있는지 분석하였으며 두 군간의 특성을 비교하기 위하여 산모 연령, 진단 시 재태연령 등을 비교하였다. 결과: 임신이 20주 이상 지속된 군의 절박유산 진단 시 심박수는 153.1±22.9로 자연유산이 일어난 군의 134.6±18.8와 유의한 차이를 나타내었다(p=0.0076). 두 군의 진단 시 임신 주수는 8.0±1.9와 7.5±1.9로 유의한 차이를 보이지 않았으며 두 군의 특성인 연령, 초산모 비율 등에는 유의한 차이가 없었다. 결론: 절박유산으로 진단 된 임신부의 경우 배아 심박수에 따라 예후에 차이를 보이는 것을 알 수 있었으며 상대적으로 심박수가 빠른 경우 예후가 좋은 것을 알 수 있었다. 또한 심박수가 110회 미만인 경우 모두에서 자연유산이 발생하여 보다 적극적 치료 및 예후에 대한 상담이 필요한 것으로 나타났다. Objective: The purpose of our study was to investigate the relationship between prognosis of threatened abortion and embryonic heart rate at diagnosis. Methods: The study group included 86 patients in which a singleton fetus with cardiac activity was initially documented. The study population was divided into successful pregnancy group (73 cases, pregnancy was maintained above 20 weeks of gestation) and spontaneous abortion group (13 cases). We compared the embryonic heart rate, age of mother, gestational age at diagnosis between two groups. Results: A significant difference of embryonic heart rate was noted between the successful group and the spontaneous abortion group (153.1±22.9 vs 134.6±18.8 beats/min, p=0.0076). There was no statistical difference in the gestational age at diagnosis (8.0±1.9 vs 7.5±1.9 weeks), the age of mother, and primi para proportion. Conclusion: The prognosis of threatened abortion was related to the embryonic heart rate. Embryos with slow heart rates had a greater risk of spontaneous abortion. All cases with slow embryonic heart rate (<110 beats/min) had occurred spontaneous abortion. Therefore, these case were needed more information and aggressive treatment.

Infrared remote controllers are widely used in controlling electronic devices due to its simplicity and convenience. This paper presents a smart phone application unifying any infrared remote controllers. We can select a device from device list menu of the application. Any new device can be added easily by downloading the protocol file of the device from protocol file server. Remote controller protocol files are stored in audio file format, and the file related to a specific menu button is transmitted through the audio jack of smart phones. The protocol file server is a standard file server, and protocol files for various devices are collected by infrared receiver module. For smart phones without infrared facility, a small infrared module translating audio signal to infrared signal is applied.

인터넷상의 다양한 응용환경에서는 개인정보 및 민감한 정보를 보호하기 위해서 안전성이 검증된 암호 알고리즘을 사용한다. 하지만 안전성이 검증된 암호 알고리즘을 사용하여도 주어진 암호 알고리즘을 적용하는 방식이 올바르지 못하면 보호하고자 하는 정보들이 누출될 수 있다는 연구 결과와 공격기법들이 소개되고 있다. 이 공격방법들 중 대표적인 사례가 패딩 오라클 공격이다. 본 논문에서는 블록 암호 기반 CBC운영모드와 CBC 패딩 방법을 적용하는 응용환경인 STRP, MIKEY, CMS, IPSec, TLS, IPTV에 대해 패딩 오라클 공격을 적용하고, 패딩 오라클 공격에 대한 공격 가능 여부 및 취약점에 관하여 연구하였다. In the various application environments on the internet, we use verified cipher algorithm to protect personal information. Even so, if an application method isn``t proper, the information you want to keep can be intercepted. One of the representative examples of it is a PADDING ORACLE ATTACK. This thesis studied about STRP, MIKEY, CMS, IPSec, TLS, IPTV, an application environment which apply CBC operational mode based on block cipher and CBC padding method, and about whether we can attack against the Padding Oracle Attack as well as the vulnerable points.

전재승,황성진,안지환,김형순,Jeon, Jae-Seung,Hwang, Seong-Jin,Ahn, Ji-Hwan,Kim, Hyung-Sun 한국재료학회 2009 한국재료학회지 Vol.19 No.8
Reflection properties, such as specular reflection and diffuse reflection, are very important optical properties for the reflector, which has high reflectance in the display and architecture industry. Calcite is lowcost, nontoxic, and stable over a wide temperature range. Therefore, it is one of the most widely using fillers in many industries and has some advantages over titania as a filler to improve reflectance. However, optical properties, especially those of ceramic-filled composites, have not been analyzed. We studied the reflectance of calcite composites with their surface roughness. The reflectance of the composites was determined using a UV-visible spectrometer. The surface morphology and the micro-structure of the composites were investigated by atomic force microscope. The reflectance of the composites was improved by increasing the content of calcite in the calcite-frit composite. The reflectance is related with the surface roughness in the composites. However, the reflectance depends on the calcite contents in materials with similar surface roughness.

The glass-ceramic based on LAS($Li_{2}O-Al_{2}O_3-SiO_{2}$) system was observed using SEM(Scanning Electric Microscopy) and AFM(Atomic Force Microscopy) and it was expected to get a correlation between the crystal size and the surface roughness through the result. At heat treatment conditions (the nucleation: $740\~800^{\circ}C$, the crystal growth: $900\~1150^{\circ}C$), the crystal size was increased from 72 to 450 nm so that the mean of surface roughness was also risen from 0.8 to 6.3 nm. Based on the results, the surface roughness of glass-ceramic is controlled by the factors, crystal size, crystallines, and the condition of heat treatment.

According to progress rapidly digitalization, networked and mobilization of electronics industry, there are demands for being smaller, thinner, more light, and more efficient complex functions of electronic devices which are wireless devices, semi-conductors, packages and mobile devices. Therefore, the solder resist on a printed circuit board have been required with the high resolution and the eco-friendly materials in the surface treatments such as high heating process and coating process with electrolysis. In this study, the photoinitiator initiator and monomers of the solder resist were prepared with their contents for reducing the occurrence of the under-cut. We investigated the sample surface by UV/VIS spectrometer, FT-IR, OM after HASL and ENIG process. From our results, it is possible to get a high adhesion of resist with optimal contents between the photoinitiator initiator and monomers after surface treatments.
